+    **🚀 This app is now MCP-enabled!** AI assistants like Claude can use it as a specialized security tool.
+    
+    ### 🛠️ Available MCP Tool:
+    
+    #### 🛡️ `analyze_smart_contract`
+    - **Purpose**: Complete smart contract security analysis
+    - **Features**: Security vulnerabilities + Risk scoring + Code quality assessment
+    - **AI-Powered**: Uses HuggingFace models with intelligent rule-based fallback
+    - **Input**: Just paste your Solidity contract code
+    - **Output**: Comprehensive security report with actionable recommendations
+    - **Reliability**: Always works - even without API tokens (fallback analysis)
+    
+    ### 🤖 How AI Assistants Use This:
+    
+    **Claude Desktop Integration:**
+    ```json
+    {
+      "mcpServers": {
+        "smart-contract-analyzer": {
+          "command": "npx",
+          "args": ["-y", "@modelcontextprotocol/server-gradio", "YOUR_HF_SPACE_URL"]
+        }
+      }
+    }
+    ```
+    
+    **Example AI Conversation:**
+    ```
+    User: "Analyze this smart contract for security issues: [paste contract]"
+    
+    Claude: [Uses analyze_smart_contract tool] 
+    "I've analyzed your contract and found 3 critical vulnerabilities..."
+    ```
+    
+    ### ✨ Key Benefits:
+    - **One-Click Security**: AI assistants can instantly analyze any contract
+    - **Always Available**: Hosted on reliable HuggingFace infrastructure  
+    - **No Setup Required**: AI assistants connect directly to your public space
+    - **Professional Reports**: Detailed analysis with specific remediation steps

+    
+    ## 🛡️ `analyze_smart_contract` - The Complete Security Tool
+    
+    **What it does:**
+    - ✅ **Security Vulnerability Detection** (reentrancy, access control, etc.)
+    - ✅ **Risk Assessment & Scoring** (1-10 scale with detailed factors)
+    - ✅ **Code Quality Analysis** (best practices, optimization opportunities)
+    - ✅ **Actionable Recommendations** (specific steps to fix issues)
+    - ✅ **Always Works** (AI-powered with intelligent fallback)
+    
+    **Parameters:**
+    - `contract_code` (required): Your Solidity smart contract code
+    - `hf_token` (optional): HuggingFace API token for AI analysis
+    - `hf_model` (optional): Model name (default: microsoft/DialoGPT-medium)
+    
+    ## 🚀 For AI Assistants (Claude, etc.):
+    
+    **Claude Desktop Config:**
